@ruslan.alikhamov THANK YOU SOOO MUCH!!! This did the trick! My system is affected since update to Xcode 13, Spotlight is running and SourceKitService, too - but now it seems it is over :)

It is absolutely useless to use push notifications as a timer. When I'm in bed, my cell phone is under the bed and sometimes has no connection. How does Apple envision it? How can I build a great alarm clock if my app only rings when there is good internet connection? With Android that's no problem at all, I can set an alarm in the time manager. As usual, it is not 100% accurate because the system may have a slightly different loop, but it is always available!

In addition, it is absolutely unclear to me how this is supposed to work in airplane mode?

I have the same question. Did you get it to work?

same on iPad M4. iOS18. Can only unsync iCloud, thats bad.

I am getting load_eligibility_plist: Failed to open, too: /Users/.../Library/Developer/CoreSimulator/Devices/F462F906-...-6453A585BBC4/data/Containers/Data/Application/B17E59FE-...-15CD3E472BCB/private/var/db/eligibilityd/eligibility.plist: No such file or directory(2)
